3# If these # comments don't work, trim them. Don't worry about any other
4# shell scripts, Configure will trim # comments from them for you.
5#
6# (If you are trying to port this package to a machine without sh,
7# I would suggest you have a look at the prototypical config_h.SH file
8# and edit it to reflect your system. Some packages may include samples
9# of config.h for certain machines, so you might look for one of those.)
10#
11# Yes, you may rip this off to use in other distribution packages. This
12# script belongs to the public domain and cannot be copyrighted.
13#
14# (Note: this Configure script was generated automatically. Rather than
15# working with this copy of Configure, you may wish to get metaconfig.
16# The dist-3.0 package (which contains metaconfig) was posted in
dfe9444c
AD
17# comp.sources.misc and is available on CPAN under authors/id/RAM so
18# you may fetch it yourself from your nearest archive site.)

29SCO csh still thinks true is false. Write to SCO today and tell them that next
30year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
31
32(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33we'd have to do is go in and swap the && and || tokens, wherever they are.)

40I will attempt to remedy the situation by running sh for you...

2304df62 1890This installation shell script will examine your system and ask you questions
a0d0e21e 1891to determine how the perl5 package should be installed. If you get
2304df62
AD
1892stuck on a question, you may use a ! shell escape to start a subshell or
1893execute a command. Many of the questions will have default answers in square
1894brackets; typing carriage return will give you the default.
1895
1896On some of the questions which ask for file or directory names you are allowed
1897to use the ~name construct to specify the login directory belonging to "name",
1898even if you don't have a shell which knows about that. Questions where this is
1899allowed will be marked "(~name ok)".

1904 . ./myread
1905 cat <<'EOH'
1906
1907The prompter used in this script allows you to use shell variables and
1908backticks in your answers. You may use $1, $2, etc... to refer to the words
1909in the default answer, as if the default line was a set of arguments given to a
1910script shell. This means you may also use $* to repeat the whole default line,
1911so you do not have to re-type everything to add something to the default.
1912
1913Everytime there is a substitution, you will have to confirm. If there is an
1914error (e.g. an unmatched backtick), the default answer will remain unchanged
1915and you will be prompted again.
1916
1917If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1918the questions and use the computed defaults (or the previous answers if there
1919was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1920You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 1921on the non-interactive behaviour for the remainder of the execution.

1927Much effort has been expended to ensure that this shell script will run on any
1928Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1929Configure and run it again. If you can't run Configure for some reason,
1930you'll have to generate a config.sh file by hand. Whatever problems you
7f2de2d2 1931have, let me (perlbug@perl.org) know how I blew it.

1932
1933This installation script affects things in two ways:
1934
19351) it may do direct variable substitutions on some of the files included
1936 in this kit.
19372) it builds a config.h file for inclusion in C programs. You may edit
1938 any of these files as the need arises after running this script.
1939
1940If you make a mistake on a question, there is no easy way to back up to it
1941currently. The easiest thing to do is to edit config.sh and rerun all the SH
1942files. Configure will offer to let you do this before it runs the SH files.

3123Perl can be built to take advantage of threads on some systems.
3124To do so, Configure can be run with -Dusethreads.

3126Note that threading is a highly experimental feature, and
3127some known race conditions still remain. If you choose to try
3128it, be very sure to not actually deploy it for production
3129purposes. README.threads has more details, and is required
3130reading if you enable threads.

3147As of 5.5.640, Perl has two different internal threading implementations,
3148the 5.005 version (5005threads) and an interpreter-based version
3149(ithreads) that has one interpreter per thread. Both are very
3150experimental. This arrangement exists to help developers work out
3151which one is better.
3152
3153If you're a casual user, you probably don't want interpreter-threads
3154at this time. There doesn't yet exist a way to create threads from
3155within Perl in this model, i.e., "use Thread;" will NOT work.

3420 In general it is a good idea to keep gcc synchronized with
